TUBULAR LANTERN.

SPECIFICATION forming part of Letters Patent No. 445,171, dated January 2'7, 1891.

Application filed March 29, 1890. Serial No. 345,851. (No model.)

.To aZZ whom it may concern.-

Be it known that I, GEORGE J. GERBER, a citizen of the United States, residing at 67 North ells street, Chicago, in the county of Cook and State of Illinois, have invented a new and usefulImprovement in Tubular Lanterns, of which the following is a specification.

This invention relates to that class of tubular lanterns which are provided with a globeframe capable of being moved up and down in the tubular lanterirframe by means of a lever pivoted to the base of the lantern to expose the burner for lighting, trimming, &e., and with a globe-fastening which permits the globe to be readily removed from the globeframe.

The objects of my invention are to facilitate the raising and lowering of the globeframe and the removal of the globe, and to provide the lantern with a simple guard by utilizing the lifting-lever as part of the guard.

In the accompanying drawings, consisting of two sheets, Figure l is a rear elevation of a tubular lantern provided with my improvement. 2 is a side elevation thereof, partly in section. Fig. 3 is a horizontal section in line a: 0;, Fig. 1. Fig. 4 is a sectional side elevation showing the globe and its support tilted. Fig. 5 is a similar view showing the globe-frame lifted from the burner.

Like letters of reference refer to like parts in the several figures.

A represents the oil-pot; a, the air-chamber secured to the top of the oil-pot, and b the burner surmounting the air-chamber.

C 0 represent side tubes secured at their lower branches to the top of the oil-pot and connected at their upper branches to the central depending tube 0.

D is the bell or air-gatherin g plate mounted on the central tube 0, so as to be capable of vertical movement thereon.

d represents a spring surrounding the central tube 0 and pressing downwardly upon the bell D.

E represents the lift wires or rods secured at their upper ends to the bell and attached at their lower ends to the globe-supporting plate t in such manner that the latter can be tilted. This connection is preferably effected by hooks formed at the lower ends of theliftwires and eyes formed on the globe-plate.

F represents the globe resting upon the plate e, and G represents the globe-spring, which is attached to the bell and holds the upper end of the globe reinovably in place. Any other globe-fastening which permits the globe to be released may be employed in place of the globe-spring, if preferred.

The bell D, lift-wires E, and plate 6 form the globe-frame, which is capable of movement up and down in the lantern-frame toward and from the burner.

H represents the lever by which the globeframe is raised from the burner. This lever is constructed in the form of an inverted-U- shaped frame and is pivoted to a standard I, which is secured to the oil-pot on the rear side of the lantern. This standard is provided with a horizontal top bar 1', on which the two branches of the lifting-lever turn. The lower branches 7b of the lifting-lever are arranged horizontally underneath the globeplate 6, and the bow shaped portion 72. of the lever-extends upwardly from the standard on the rear side of the globe and forms the rear guard.

J represents the front guard, composed of an inverted-U-shaped frame similar in form So to the liftinglever ll, and secured with its lower horizontal portions to the underside of the globe-plate so that the latter and the front guard tilt together. The ends of the front guard are provided with eyesj, in which 8 5 engage outwardly-proj ecting pivots 7i, formed on the ends of the lifting-lever, whereby the latter is connected with the globe-supporting plate 6. hen the globe-frame is in its normal position, the globe-plate rests upon the 0 burner and the front and rear guards extend upwardly on the front and rear sides of the globe, as represented in Figs. 1 and 2. The globe-frame is held in this normal position by the downward pressure of the spring upon 5 the bell.

When it is desired to remove the globe, the globe-spring or other globe-fastening device at the top of the globe is released and the globe is tilted forward, as representedin Fig. I00

4. This movement of the globe eau'ses its supporting-plate to tilt on the pivots 7a of the lifting-lever and on the hooks of the lift-wires. During this tilting movement of the globe the front guard forms a support for the globe and prevents the latter from falling out of the globe-frame if it should beinadvertently released.

hen it is desired to lift the globe-frame from the burner in order to reach the latter for trimming, lighting, or other purposes, the upwardly-projecting main arm of the liftinglever' is swung downwardly, as represented in Fig. 5. This causes the upper end of the globe-frame to move upwardly on the central tube and the lower end of the globe frame to swing upwardly and baokwardly. As the bell moves upwardly on the central tube the spring surrounding; the latter is compressed until the short arm of the litting-lever has passed the dead-center, when the reaction of the spring causes the lifting-lever to continue its movement until its long arm strikes the oil-pot, as represented in dotted lines in Fig. 5, or some other stop which arrests its movement and causes the globe-frame to remain.

in its elevated position. Upon reversing the movement of the lifting-lever the globe-frame is lowered and returned to its normal position on the burner.

I claim as my invention- 1. The combination, with the tubular lantern-frame and the globe-frame capable of movement up and down in the tubular frame, of a lifting-lever pivoted to the base of the tubular frame and having its outer arm extending upwardly along the outer side of the globe and forming a guard, substantially as set forth.

2. The combination, with the tubular lantern-frame and the globe-frame capable of movement up and down in the tubular frame, of a guard arranged on one side of the globe and secured to the globe-frame, andaliftinglever forming a guard on the opposite side of the globe, substantially as set forth.

Vitness my hand this 24th day of March, 1800. V

GEORGE J. GERBER.
